I experienced some intermittent hesitation on acceleration with a 2000 323i with only 67K miles on it and it was the fuel pump going bad. Get a VDO one and you will have some peace of mind even if it does not address your issue, better safe than getting stranded somewhere.

 

Ok I was also having trouble with , oil getting in my spark splugs .. but the valve cover gasket should have taken car of that right ? . I got one from the dealer .. how much does a fuel pump go for ?

A VDO fuel pump is About $150 and easy to change, consider a fuel filter at the same time, mine was about $60+. Pull the disa out and inspect it, the flapper broke off the bell crank on mine and threw codes before it started misfiring. I got lucky and only lost a little of the plastic, the pin was still there but it had backed out just a little. Even if it's not causing your issues I'd inspect yours and consider the German American Solutions rebuild kit. $78 is worth the piece of mind about losing that pin into the intake manifold.

 

I will look into it this weekend , thanks yeah that might explain the cylinder missfire codes . I will just be extra careful about pulling the disa out . Thanks a ton I appreciate it .

The fuel pump might also explain the whistling noise I've been hearing when I accelerated.

Here are the codes from my peake reader
E3 O2 sensor adaption cyl 1-3
E4 O2 sensor adaption cyl 4-6
EE misfire cyl 1
EF misfire cyl 2
FO misfire cyl 3
F1 misfire cyl 4
F2 misfire cyl 5
I used my cheap OBDII reader and got lean codes and some O2 sensor codes too but didn't write them down.

 

Sweet thanks man

Was the misfiring happening before the valve cover gasket? If not, did you hook up the ignition coil grounds properly? There are two.

If I looked up the codes correctly, then you have 4, 5, 6 misfiring which is a whole bank. Strange that the other bank (1, 2, 3) wouldn't misfire as well if it were something like fuel delivery or a vacuum leak. You have no lean codes??

A DISA shouldn't cause symptoms this bad. Usually they just leak a cause a lean code.

 

Mine ran like $h!t shortly after the light came on, fixed the disa and so far it runs great. No misfires or codes.

 

Have you performed a smoke test? Google how to perform a home smoke test. It'll expose any leaks. Maybe your DISA leak is huge. It's possible. If it's leaking from the DISA, then I'd rebuild the DISA with a GAS kit that includes the O-ring.
